I guess "transient" is more descriptive.
Actually, thinking on it some more, I don't think that transient will work at
all, and the reason is simple. _Which_ operation should you retry?
The application decides.
You don't
even necessarily know which function the exception came from out of the
functions that you called within the try block - let alone which function
actually threw the exception. Maybe it was thrown 3 functions deep from the
function that you called, and while retrying that specific call 3 functions
down might have made sense, retrying the function 3 functions up doesn't
necessarily make sense at all.
Whether or not you can retry or retrying makes any sense at all is _highly_
dependent on who actually catches the exception. In many cases, it may be a
function which could retry it, but in many it won't be, and so having the
exception tell the caller that it could retry would just be misleading.
No dependence on context. The bit simply tells you "operation has
failed, but due to a transitory matter". That is information local to
the thrower.
